WarMovies, it definitely sounds like you got the knowledge of how it all works now.....and hopefully others who may read this forum in the future will understand it too.
As been stated, you will need a large battery bank to run inverters that will output the necessary AC power you may need. These inverters come in different sizes, and the more they output, the more battery capacity you need. The size and weights of having several batteries(bank) are definitely a limiting factor. You usually only see large inverters in larger motorhomes, etc......although they can certainly be installed in trailers if needed per application.
Here is a fairly good article that you may find interesting, and you probably will understand it all now. It also has recommendations on wire sizes, etc. I just scanned over the article and didn't verify the sizes, but it's probably correct.
